BTO Research Reports

BTO Research Reports

BTO Research Reports are scientific papers that have been self-published by the BTO. The following is a full list of the published BTO research reports, which includes BBS reports, Waterbirds in the UK (WeBS) reports and SMP reports. Most are free to download, and links to Abstracts are included where possible.

Numbers missing from the list are those allocated but which were never produced or which have not been published. BTO recognises that, particularly in respect of commercially sensitive cases, a period of confidentiality is appropriate for some projects. However, in the interests of scientific development and dissemination of information, we encourage clients to permit publication as soon as it is reasonable to do so.

Improving understanding of the possible relationship between improving freshwater and coastal water quality and bird interest on designated sites - phase 1 review

Author: Henrietta E K Pringle, Niall H K Burton

Published: 2018

Over the past 50 years there has been widespread improvement in water quality in many freshwater and coastal systems driven by domestic and European legislation, most recently the EU Water Framework Directive (EC Directive 2000/60/EC), but also including the Urban Waste Water Treatment Directive (EC Directive 91/271/EEC) and Bathing Water Directive (EC Directive 76/160/EEC).

Assessing the habitat use of Lesser Black-backed Gulls (Larus fuscus) From the Bowland Fells SPA.

Author: Clewley, G.D., Scragg, E.S., Thaxter, C.B. & Burton, N.H.K.

Published: 2017

The Bowland Fells Site of Special Scientific Interest (SSSI) and Special Protection Area (SPA) is located to the east of Lancaster within north Lancashire. It supports the largest area of blanket bog and heather moorland within Lancashire and provides a habitat for an internationally important upland breeding bird community. The diverse mosaic of upland habitats across the Fells contributes greatly to the ornithological interest of the site, which supports breeding Hen Harrier (Circus cyaneus) (at its only regular breeding site in England), Merlin (Falco columbarius) and one of the five largest UK breeding colonies of Lesser Black-backed Gull (Larus fuscus), which is a SPA review (Stroud et al. 2001) and pSPA (potential SPA) feature.
